As you would realise they are the axle bearing numbers and seals etc
The only other info I have for the diff is that the Front and Rear seals for the diff pinion is National 9316. They are the same.
Hope some one can come up with the numbers for you for the diff centres

thanks Tony, they are the wheel bearings.

pinion inner bearing is the one I'm chasing
Dana 60 is hm803110 & hm803146
Dana 70 is a bigger bearing??

I was hoping someone has the no, save me stripping another diff to get the no..
all the part mob's want to sell you a kit & won't give the bearing on its own or the no!!!

my AGG bearing suppler in Narrogin is good price wise, a Cummins idler pulley from Cummins $480
from him $84 it pay's to shop local!!

Hi Brett,

Just completed a full bearing and diff center change on 351.

Small pinion bearing HM88542 with HM88510
Large pinion bearing HM803149 with HM803110

Both Timkin USA bearings. These were removed so just did a check

Cheers Brian

Hello,

after travelling for 3 months along rough tracks in Africa my left side half shaft at the rear axle broke (please see attached
pictures).
The half shaft is a 32 spline!

Now I am in urgent need for a new one. Where to try?

Since I am in South Africa that is difficult. Though about going through the scrap yards looking for an old axle.
Does anybody know which vehicles had a Dana 70 axle so that I can start looking?

I assume welding a half shaft is not a good idea?
Thanks for your input and help!

Thank you and best regards

OIA,I may suggest that you upgrade to 35 splines if you can other ways try East coast gear supply in the US you can buy the axle with about 6" of splines and cut it to suit,also OKA parts will have the axle in stock give Dean a call on +61418943230,if you're stuck I may have a second hand shaft in the workshop but I'm going away for four days but can pack it on Monday if needed you can txt me on +61419322443 if that is of any help

OIA, the Dana 70 was used in a wide range of vehicles, some of which were probably available in SA.

This list is from The Drivetrain Shop .

Popular Applications:
Dodge W200 - W350 1960 - 1993 F / R
Dodge D250 / D350 1965 - 1993 Rear
Ford F-250 Super Duty 2001 - 2011 Rear
Ford F-350 (Super Duty) 1980 - 2002 Rear
Dodge Ram 2500 / 3500 1994 - 2002 Rear
Chevy C30 / C35 1974 - 1998 Rear
GMC K30 / K35 1970 - 2000 Rear

But note that there were many variants of the Dana 70. As Joe says, you might need to contact Oka Parts in Perth for specific Oka dimensions. A 35 spline upgrade would be well worthwhile and ECGS have all the parts you might need.

This Pirate 4x4 website contains more info than you'd ever need.

OIA,just had a look at your broken axle photo it's very close to the end,before you order anything remove the carrier and make sure the spider gear is ok and have not damaged the splines,if the splines are damaged you may as well upgrade to 35 splines and never have a broken axle again.

Thanks for your reply,
I am trying to stick with the 32 splines for now if no other components are damaged. I am just trying to remove the diff components. However, I do only have a maintenance manual for the Dana 60.

Although I assume it is very similar to the Dana 70, does anyone have a maintenance manual for the Dana 70?

I am still looking for the shaft in below WANTED poster:

OIA, there is a Dana 70 manual in our Tech Docs library:

Dana 70 Manual (9MB)

This might be of assistance.

Removing the diff centre is fairly simple, remove axle shafts and bearing cup retainers and it should almost fall out, but it is very heavy. Then you can inspect the spider gears more closely.

Putting the centre back I found quite difficult due to its weight and the fact that you have to hold both bearing caps in place, engage the carrier ring with the pinion and with your third hand fit the bearing retainers.

I have now removed the diff carrier. Unfortunately the shaft did break very close to were the splines begin.
All the lose metal did damage about 4mm of spline area and did grind holes into the carrier.
I do assume the holes would not be that bad but the missing spline teeth area will reduce the contact surface between spline and carrier.
The gears seem to be all ok and not damaged by the shaft debris.

However I am now considering upgrading to 35 spline since I might have to change the carrier. What parts do I need to buy in order to do this upgrade?

If I am investing that kind of money I might as well install a limited slip differential - any suggestions and recommendations?

OIA, if you upgrade to a 35 spline LSD you'll only need 2 35 spline axle shafts unless the ring gear is damaged (since it's reused). However, new carrier bearings and ring bolts are recommended and you will need to set up the backlash with shims since the carriers won't be exactly the same size. Best to buy a complete install kit (eg like this one from ECGS ).

Special set up bearings (or old ones honed out) are useful since they are easier to install and replace when setting up the shim thickness.



When I fitted an LSD, I took my axle out as it was easier to work on and set up the gears. Note I also had to shorten one of my axle shafts by a few mm so it wouldn't interfere with the LSD cross shaft.

I should have re-shimmed the pinion and fitted new pinion bearings as well while the carrier was out since I have some slight play in the pinion shaft. Too late after the carrier is back in.

There's plenty of on-line advice eg here and here .

It was not a quick job (for me) and no doubt others will have alternative advice.
